To all whom it may concern.-

Be it known that 1, 'W LLIAM' E. HASKELL, of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Organs, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates generally to the members of an organ which distribute the wind and control the admission thereofto the sounding devices.

My invention comprises improvements in' the construction and relative arrangement of the soundboard,the wind-chest, and the pneumatic-levers which control the admission of wind through the soundboard to the sounding devices hereinafter more definitely'speci within said partition-bars arewind-ducts leading to pneumatic-bellows levers fixedin vertical position upon'said partition-bars in the v respective wind-chambers and arranged to control the admission of wind from said chambers to the respective sound-pipes. In the practice of my invention I construct a sounding-board of two series of narrow slats, the respective series being horizontally disposed at right angles to each other in'such latticed relation that air-spaces exist between the adjoining slats in each series, which arrangement permits theindividual slats to expand and contract independently without disturbance of the required relation of the component parts of the board; Moreover, the airducts leading to the pneumatic levers are formed in said horizontal slats instead of in the vertical partition bars, as heretofore.

The ordinary pneumatic-bellows levers being iiXed in an ordinary wind-chest, as aforesaid, in vertical position upon the partitionbars, an essential element of such a lever is a spring operatively connected with its bellows to expand the latter. It is found in practice that in each operation of such a spring-provided bellows to open the valve with which it is connected there is an appreciable delay due to the'fact that thewind pressure exerted upon the bellows must be continued without movement of the lever until not only the inertia of the latter, but also the stress of the spring, is overcome. As hereinafter described, in the practice of my invention the pneumatic-bellows levers are so constructed and arranged as to be operative Without theemployment of springs, being so balanced as to respond instantly to either internal or external pressure.

Inthe accompanying drawings, Figure 1 is a sectional view of a partial organ conveniently embodying my invention. Fig. 2 is an enlarged sectional View of the soundboard, wind-chest, 850., shown in Fig. 1. Fig. 3 is a sectional View taken on the line 3 3 in Figs. 1 and 2. Fig. 4 is a sectional view taken on the line 44in Fig. 3. Fig. 5 is fragmentary plan view showing the latticed construction of the soundboard.

Referring to Fig. l, A is the manual, whose digitals a are respectively connected with themanual-action valves I). Said valves control the admission of wind from the manna-Laction box B through the ducts c to the respective primary pneumatic-bellows 0. Each of saidprimary pneumatics O is provided with a pressure-valve c and an exhaust-valve 0 coupled by a rod 0 to control the admission ofwind from the primaryvalve-box D through the respective conduits dto the intermediate pneumatic-bellows e. Said pneumatics care each provided with a pressurevalve 6 and an exhaust-valve 6 coupled by a rod c to con trol the admission of wind from the intermediate valve-box E to the soundboard F. Said soundboard F comprises a series of parallel top slats fanda series of parallel bottom slats f, fixed in right-angular latticed relation, as indicated in the several figures, the adjoining slats in each series being slightly separated to permit of independent contraction and expansion of the respective slats. The bottom slats f are provided with internal wind-ductsf which are respectively in communication with the valve-box E by the'openings f and comprise branch open-" ings f extending through the bottom of the soundboard, and the several pneumatic-bars g g g g. Said bars are fixed to the soundboard parallel with the top slats f and form the respective tops of the separate unit windboxes G G G G", which constitute the windchest G.

The sound-pipes in the registers H H II II" are provided with individual seats h in the top slats f of the soundboard F, and said pipes are respectively connected with the wind-boxes by the ports h h2 h h, which extend from said seats through the top and bottom slats f f and pneumatic-bars g &c., into the respective wind-boxes G G &c. The pneumaticbars g g g g" respectively support the pneumatic-levers I I I I in horizontal position on the under side of the soundboard F and within the respective windboxes I, the. Each of said levers comprises a pneumatic-bellows whose cheek-piece 2' is fixed in registry with the respective ductopening f and a lever cheek-piece i, hingedly connected to said fixed cheek-piece by a flexible inclosure i Each of said levers also comprises an arm i fixed upon the movable cheek piece e" and provided at its extremity with a valve 1' in registry with the respective valveports 7b 712, (he.

The wind-chestG proj ectsbeyond the sounding-board F, as shown in Fig. 3, and supports the register stop-box J, which is connected with the supply of compressed air by the wind-trunk K. The admission of wind from said stop-box J to the respective units Gr, G G and G of the wind-chest is separately effected by the respective stop-pneumatic bellows J, J J and J, each of said pneumatics being provided with a pressurevalve j and an exhaust-valvej coupled by a rod j. Said stop-pneumatics J, &c., are independently connected with the primary stop-valve box L by means of the respective wind conduits L L L L and the admission of wind to said conduits L, &c., is effected by respective valve-levers m each provided with a pressure valve on, and an exhaustvalve m coupled by a valve-rod m said levers in being arranged to be independently controlled by the respective digitals n 073, &c. of the stop-manual N.

The operation of the device above described is as follows: It being desired to usetheregister of pipes H,the digital n of the stop-manualN is depressed, as indicated in Fig. 1,which opens the conduit L to the atmosphere and permits the stop pneumatic J to be collapsed, as shown in Fig. 4, by the wind within the box J, thus admitting the wind to the wind-chest box G common to said register H. The pneumatic-pressure thus produced in the box I being external to the pneumatic-lever I is balanced by the pneumatic-pressure within the bellows of said lever, while said bellows remains in communication with the wind-box E by the duct f dsc. However, if any one of the digitals a in the manual A is depressed c is closed and its valve 0 opened, admitting wind from the primary valve-box D to the respective intermediate pneumatic e, thereby closing its valve 6 and opening its valve c which opens the corresponding duct f to the atmosphere, so that the bellows of the respective lever I is instantly collapsed and opens the respective port h leading to the particular pipe of the register H corresponding to the digital adepressed, thereby causing that pipe to speak. To terminate the action of said pipe, the depressed digital a is released, the valve 1) is closed, the pressure falls within the respective duct 0 by means of the escape of wind from the exhaust-vent 0 leading from each duct to the atmosphere, and the pneumatic O is collapsed by the windpressure upon the valve 0 within the box D, thus closing said valve 0 and simultaneously opening the valve 0 Opening of the valve 0 permits the pressure in the intermediate pneumatic e to escape, and said pneumatic is collapsed by the pressure within the intermediate valve-box E, thereby opening the valve e and simultaneously closing the valve e so that pressure is admitted to the bellows of the lever I, and the latter gravitates to its normal position, wherein its valve 2' closes the port h leading to said pipe.

The embodiment of my invention which I have illustrated comprises an automatic playing device 0, consisting of a wind-casing 0, containing the tracker-bar 0, which is provided with apertures equal in number to the digitals of the manual A, which apertures are respectively connected by the conduits 0 with the respective ducts c. Said casing O also contains the rollers P P, which cause i the traverse of a perforated sheet of fabric Q over the tracker-bar 0 to admit wind to operate any selected sound-pipe, as will be readily understood. However, I do not desire to limit myself to the particular embodiment of my invention which I have illustrated, as it is obvious that various modifications may be made therein without departing from the essential features of my invention.
